Found only on Carnival, Faster to the Fun (FTTF) is an extra-fee add-on that gives regular, non-suite passengers priority when it comes to boarding, disembarking and making onboard reservations.

Faster to the Fun (FTTF) is a popular, limited-capacity "add-on" package that passengers can purchase to receive VIP-style perks without needing high-level loyalty status. The primary benefit is Priority Embarkation, allowing you to bypass the standard long lines and board the ship shortly after the Diamond and Platinum members. Other key perks include Early Stateroom Access (your cabin is ready as soon as you board, so you can drop off your bags), Priority Luggage Delivery (your checked bags arrive at your door sooner), and Dedicated Guest Services (a special phone line and a shorter physical line at the desk). It also provides Priority Tender Access in ports where the ship anchors offshore and Priority Debarkation on the final morning. The price varies by the length of the cruise, and because it is highly sought after and limited to a small number of cabins, it often sells out months in advance through the "Shore Excursions" section of the Carnival website.
